There has been a very noticeable increase in air pollution during the past ten years over and downwind of the several large metropolitan areas of the United States such as the Northwest—Vancouver-Seattle-Tacoma-Portland; the West Coast from San Francisco-Sacramento-Fresno-Los Angeles; the Front Range of the Rockies from Boulder-Denver-Colorado Springs-Pueblo; the Midwest—Omaha-Kansas City-St. Louis-Memphis; the Great Lakes area of Chicago-Detroit-Cleveland-Buffalo; and the Northeast—Washington-Philadelphia-New York-Boston. The worst accumulation of particulate matter occurs at the top of the inversion which commonly intensifies at night at levels ranging from 1000 to 4000 ft or so above the ground. This dense concentration of air-suspended particles is most apparent to air travelers. Thus, it has not as yet disturbed the general public except during periods of stagnant weather systems when the concentration of heavily polluted air extends downward and engulfs them on the highways, at their homes and in their working areas.

In the 1970s, Japanese cooks began to appear in the kitchens of nouvelle cuisine chefs in France for further training, with scores more arriving in the next decades. Paul Bocuse, Alain Chapel, Joël Robuchon, and other leading French chefs started visiting Japan to teach, cook, and sample Japanese cuisine, and ten of them eventually opened restaurants there. In the 1980s and 1990s, these chefs' frequent visits to Japan and the steady flow of Japanese stagiaires to French restaurants in Europe and the United States encouraged a series of changes that I am calling the “Japanese turn,” which found chefs at fine-dining establishments in Los Angeles, New York City, and later the San Francisco Bay Area using an ever-widening array of Japanese ingredients, employing Japanese culinary techniques, and adding Japanese dishes to their menus. By the second decade of the twenty-first century, the wide acceptance of not only Japanese ingredients and techniques but also concepts like umami (savory tastiness) and shun (seasonality) suggest that Japanese cuisine is now well known to many American chefs.

The Environmental Protection Agency promulgation of “Control of Emissions of Air Pollution from New Marine Compression Ignition Engines at or above 37 kW,” on December 29, 1999, marked the first time federal air pollution regulations were directly applied to marine engines for commercial U.S. ships. Perhaps surprisingly, these regulations are not having as much impact as are individual State Implementation Plans (SIP) for Nitrogen Oxides (NOx) attainment, and local political pressures. These regional plans and pressures are forcing many domestic marine operators and ports to get a quick education on the cause and mitigation of air pollution. Cases in point, include: • The State of Alaska now fines passenger vessels that enter ports with greater than allowable stack gas opacities. One cruise operator has opted to plug into shore power when its vessels are tied up to pier. • In the Ports of Los Angeles and Long Beach vessel operators have been asked to slow vessel speeds below normal while entering and exiting in a voluntary attempt to reduce NOx emissions. • Environmentalists in the San Francisco Bay Area are applying significant political pressures to ensure proposed new ferry systems emit a minimum of air pollution. • The State of Texas briefly considered stopping all industrial equipment in the Port of Houston for twelve hours per day as a method of decreasing area ozone formation. • Potential NOx emissions generated during imminent channel dredging in the Port of New York and New Jersey is impeding the development of the latest State Implementation Plan. Local pressures are likely to continue to grow, federal regulations are set to become more stringent, and international conventions loom on the horizon. However, as expected in such a competitive industry, concerns are often focused on the bottom line in which cost of operations is a pre-eminent factor. It was in view of these dynamics that the federal Maritime Administration (MARAD) recently launched the Maritime Energy and Clean Emissions Program. This paper introduces the Program, including the background, evolution, and progress of each strategic goal. This paper is intended to be an overview. Attention is paid to the potential transferability and/or development of technologies not previously deployed in the U.S. marine environment. Any of the specific projects described could become the basis for a separate technical paper.

In at least one sense the “American century” is ending much as it had begun: the United States has again become a nation of immigrants, and it is again being transformed in the process. But the diversity of the “new immigration” to the United States over the past three decades differs in many respects from that of the last period of mass immigration in the first three decades of the century. The immigrants themselves differ greatly in their social class and national origins, and so does the American society, polity, and economy that receives them—raising questions about their modes of incorporation, and challenging conventional accounts of assimilation processes that were framed during that previous epoch. The dynamics and future course of their adaptation are open empirical questions—as well as major questions for public policy, since the outcome will shape the future contours of American society. Indeed, as the United States undergoes its most profound demographic transformation in a century; as inexorable processes of globalization, especially international migrations from Asia, Africa, and the Americas, diversify still further the polyethnic composition of its population; and as issues of immigration, race and ethnicity become the subject of heated public debate, the question of incorporation, and its serious study, becomes all the more exigent. The essays in this special issue of Sociological Perspectives tackle that subject from a variety of analytical vantages and innovative approaches, covering a wide range of groups in major areas of immigrant settlement. Several of the papers focus specifically on Los Angeles and New York City, where, remarkably, fully a quarter of the total U.S. immigrant population resides.

This research focuses on the frequent and persistent problem of truck shortages for time-sensitive, perishable produce shipment out of the Pacific Northwest. Washington State is the number one apple-producing state in the United States, accounting for more than 2.7 million tons of apples per year valued in excess of $1 billion. However, without timely and accessible transportation to move the product from production to the consumer's table, the value to apple producers and the state's economy diminishes rapidly. This research aims to identify and quantify the change in total transportation cost that occurs as a result of seasonal truck shortages and associated rate increases and to provide an avenue for evaluating changes in specific destination markets, modal changes, and market competitiveness. A cost-minimizing optimization model is used to represent apple shipments from 29 producing supply points to 16 domestic markets and three international export markets over four seasons for two modes (truck and rail). Total transportation costs increase nearly $12 million as a result of truck shortages, from $245.6 million without shortages to $257.5 million under the current seasonal situation. Overall (across all seasons), the export markets of Nogales, Arizona; McAllen, Texas; and the Port of Seattle, Washington, are most affected by the truck shortages, followed by domestic markets near Seattle and San Francisco, California. The large markets of New York City, New York, and Los Angeles, California also experience relatively large increases in transportation cost per ton mile.

I ought to point out first that my own practice is primarily corporate practice dealing with international business between Japan and the United States. Contract drafting is probably what I do most of, that and contract negotiations. In my field, many of the negotiations are not polite; they involve role playing on both sides and often extreme misunderstandings on both sides. I think, in addition to a good law background, the most important element in practice, especially in relations between Asia and the United States, is knowledge of an Asian language and a cultural familiarity with the countries where you specialize. To be able to communicate with your own client, and to be able to communicate for your client with the Japanese company across the table, knowledge of the language is absolutely essential. Also, I think my type of practice—that is practice with Asia—illustrates something that has happened in American law practice during the last ten years. The causes are primarily the revolution in transportation and something called the telex machine. Before 1960 it was impossible to get to Tokyo from New York in less than 26 hours. Now I go almost every month; it takes 16 hours. If you are representing Japanese clients in the United States it is necessary, I think, to meet the people in the Tokyo home office. Japanese abide greatly by this type of personal contact. It also helps to eliminate misunderstanding between a lawyer and his client. More and more lawyers, especially out of New York, Chicago, Los Angeles, San Francisco, and Washington are traveling around the world with their practices following them. If you have support services in various cities, there is usually no problem. You can travel, especially if your secretary and the people you work with out of the office from which you originate can handle the minor problems that come up. The telex machine has become extremely important. This is partly because of the time lag. Japan is almost exactly twelve hours opposite from the United States. My clients’ legal departments can handle minor negotiations and telex questions to me or ask me to draft particular positions. By getting background by telex, I can do this on an overnight basis so that in effect their legal department works 24 hours a day. This has the added benefit that sometimes the Japanese clients are able to disguise from the opposing American side the fact that they are using a large New York law firm.

When I last had the honour to address this Society, I was on the point of starting for a tour in America. During some eight months I traversed the United States from sea to sea, from Boston to Virginia and from New York to Los Angeles, San Francisco and Seattle, finishing up in Canada, which I crossed from Victoria and Vancouver to Quebec and Montreal. I visited many universities and colleges and lectured at some thirty of them. I inspected numerous libraries and had speech with many score of historians. There was much that was. wonderful and strange to see and hear, but it was seldom that I could realise that it was a foreign country. If Quebec seemed a city of a France that had known no Revolution, and Santa Fe took one back to a small Spanish city with an intrusive Anglo-American element, the common tongue was a great link between the wanderer and his new friends, and he was never more bucked up than when he was assured by a leading newspaper of no mean city that, despite his strong English accent, his public orations were nearly always easily intelligible!

Artists of Asian descent made substantial contributions to the artistic culture of the United States, incorporating practices that were different from the European-based traditions—like painting with water-soluble pigments rather than oil paint, choosing Asian subjects, and signing their works in the Asian fashion. Coming across the Pacific Ocean, some immigrants settled in Hawaii where Isami Doi, born of Japanese parents, became an influential artist. Doi typifies characteristics that are found in many Asian American artists in that he excelled at several media: printmaking, painting, and jewelry design. And he traveled extensively, spending time in Paris and over a decade in New York. The West Coast of the United States became a center for people coming across the Pacific, and major cities like Seattle, San Francisco, and Los Angeles developed Asian communities with active artistic cultures. Chinese immigrants were drawn to the San Francisco area because of the economic boom around the gold rush and the building of the railroads, but they also inspired prejudice, and harsh immigration laws were enacted in 1888. This halted immigration from China and bolstered it from Japan, until another law in 1924 restricted that as well. Yun Gee, of Chinese descent, in San Francisco made aggressively modern, brightly colored, and geometrically abstracted portraits before moving to Paris and then New York where his style became more expressionistic. The Asian communities in Seattle and Los Angeles included artists who worked in photography as well as painting, and some moved further east across the United States to pursue their careers in the Midwest or, more commonly, New York, the artistic center of the country. In the 1920s and 1930s, Yasuo Kuniyoshi became well known in the New York art world for his sensitively handled, sometimes humorous, sometimes erotic paintings and prints. Nevertheless, he and his peers who were born in Asia were forbidden by law from becoming citizens, something he desired, as his entire artistic career was in the United States. The sculptor Isamu Noguchi came to prominence after being nurtured by some of the Japanese American artists in Kuniyoshi’s circle, particularly Itaro Ishigaki. Noguchi is best known for the organically shaped carved stone sculptures he made after World War II, but he was also famous as a designer of modernist furniture and lamps using Japanese materials. Both he and Kuniyoshi suffered after the Japanese bombing of Pearl Harbor in 1941, while on the West Coast Japanese Americans were herded into detention camps, often losing their jobs and their homes in the process. Chiura Obata, for example, was removed from his prestigious teaching position at the University of California at Berkeley and put in a camp where he taught art. There he switched from making luminous landscapes of Yosemite to painting camp scenes of confinement and regimentation—once he was allowed to paint at all. The postwar years were a period of recovery, and new generations of Asian American artists emerged, exploring abstract styles and creating new incarnations of the multicultural art that was pioneered in the works of their Asian American predecessors.

Throughout the era of the Mexican Revolution, the United States provided sanctuary for thousands of political exiles who opposed the regimes of Porfirio Díaz, Francisco Madero, Victoriano Huerta, and Venustiano Carranza. Persecuted enemies of Don Porfirio and losers in the bloody war of factions that followed the ouster of the old regime continued their struggle for power from bases of operation north of the international boundary in such places as San Francisco, Los Angeles, El Paso, San Antonio, New Orleans, and New York. As a consequence, Mexican regimes were compelled not only to combat their enemies on domestic battlefields but also to wage more subtle campaigns against their adversaries north of the Río Bravo. The weapons in this shadowy war included general intelligence gathering, surveillance, espionage, counter-espionage, and propaganda; the agency most responsible for these activities was the Mexican Secret Service.

Abstract. The regional concentrations of airborne ultrafine particulate matter mass (Dp<0.1 µm; PM0.1) were predicted in 39 cities across the United States (US) during summertime air pollution episodes. Calculations were performed using a regional source-oriented chemical transport model with 4 km spatial resolution operating on the National Emissions Inventory created by the U.S. Environmental Protection Agency (EPA). Measured source profiles for particle size and composition between 0.01 and 10 µm were used to translate PM total mass to PM0.1. Predicted PM0.1 concentrations exceeded 2 µg m−3 during summer pollution episodes in major urban regions across the US including Los Angeles, the San Francisco Bay Area, Houston, Miami, and New York. PM0.1 spatial gradients were sharper than PM2.5 spatial gradients due to the dominance of primary aerosol in PM0.1. Artificial source tags were used to track contributions to primary PM0.1 and PM2.5 from 15 source categories. On-road gasoline and diesel vehicles made significant contributions to regional PM0.1 in all 39 cities even though peak contributions within 0.3 km of the roadway were not resolved by the 4 km grid cells. Cooking also made significant contributions to PM0.1 in all cities but biomass combustion was only important in locations impacted by summer wildfires. Aviation was a significant source of PM0.1 in cities that had airports within their urban footprints. Industrial sources, including cement manufacturing, process heating, steel foundries, and paper and pulp processing, impacted their immediate vicinity but did not significantly contribute to PM0.1 concentrations in any of the target 39 cities. Natural gas combustion made significant contributions to PM0.1 concentrations due to the widespread use of this fuel for electricity generation, industrial applications, residential use, and commercial use. The major sources of primary PM0.1 and PM2.5 were notably different in many cities. Future epidemiological studies may be able to differentiate PM0.1 and PM2.5 health effects by contrasting cities with different ratios of PM0.1∕PM2.5. In the current study, cities with higher PM0.1∕PM2.5 ratios (ratio greater than 0.10) include Houston, TX, Los Angeles, CA, Bakersfield, CA, Salt Lake City, UT, and Cleveland, OH. Cities with lower PM0.1 to PM2.5 ratios (ratio lower than 0.05) include Lake Charles, LA, Baton Rouge, LA, St. Louis, MO, Baltimore, MD, and Washington, D.C.

Die Blaue Vier [The Blue Four] was founded in Weimar in March 1924 at the initiative of Galka E. Scheyer, who became the American representative of the four artists Lyonel Feininger, Alexei Jawlensky, Wassily Kandinsky, and Paul Klee. Although implying a direct link with and a continuation of the spiritual orientation of Der Blaue Reiter [The Blue Rider], the association was essentially a public relations effort—an attempt to put the works of the four artists under a common name in order to exhibit and sell their works successfully in the United States. Between 1925 and 1944, Scheyer organized Blue Four exhibitions in New York, Palo Alto, San Francisco, Oakland, Los Angeles, San Diego, Portland, Spokane, Seattle, Mexico City, Santa Barbara, Chicago, Northampton, and Honolulu. In the 1930s, Scheyer, believing that she could better present the artists’ work in a suitably arranged private setting, built a small gallery house on Blue Heights Drive in Hollywood. Scheyer’s personal collection of works by the Blue Four is now a part of the permanent collection of the Norton Simon Museum in Pasadena.
